NITRO BLACK VALVES
21-4N High Strength Stainless Alloy Swirl Polished for Improved Flow Characteristics Fully Undercut Stem Hard Wafer Tip One Piece Forging Proprietary Liquid Nitriding Process that Creates a Valve that is Smoother, Stronger and More Corrosion Resistant than Traditional Chromed Valves Deep Nitriding Provides Better Ductility Under the Hard Nitrided Layer as Proven in Rotating-Bending Fatigue Tests Valve is Less Likely to Break Even if Contacted by the Piston Greater Surface Hardness Means Less Valve Guide Wear Improved Corrosion Resistance even with Exotic Fuels Our Nitriding Process is Much Cleaner than Chroming- its Better for the Environment |

NEW NITRO BLACK DIESEL
PERFORMANCE VALVES
Our diesel performance valves are designed to perform reliably in the extreme conditions that exist in highly boosted turbo diesel engines. Bi-metallic exhaust valves are made from inconel and HNV-3 alloys and are stellite faced to operate under extreme heat conditions. Intake valves are made from 21-4N alloy steel. Both intake and exhaust valves are put through our proprietary five step liquid nitriding process, resulting in valves that are smoother, stronger and more corrosion resistant than traditional chrome plated stainless valves. |
For Ford Powerstroke, GM Duramax and Dodge
Cummins Engines FEATURES Exotic inconel alloy is designed to function in extreme heat and stress conditions Stellite facing creates additional heat resistance on the head of the valve Liquid nitriding strengthens the entire valve material - not just the surface area Better ductility beneath the extremely hard magnetite outer layer makes the valve less likely to break, even if contacted by a piston Greater surface hardness reduces crack formation Smoother, stronger surface means less valve and valve guide wear than chrome Resists corrosion and deposits caused by exotic fuels |

The valves below are from SI Industries
Replacement Series Valves
These valves are made from stainless and steel materials
that are suitable for all STOCK rebuilds and unleaded conversions.
Low prices and top quality make these valves a great deal for
standard use. Available for foreign, domestic and motorcycle applications. |
Seat Saver Valves
is
proud to introduce our newest series of valves. Seat Savers will
save you time and money by allowing you to save work on seats
by offering economically priced replacement valves in .030"
oversized heads. All other specs on the valves are STOCK. This allows you to still use the valve guides of your choice. |
Economical Portflow Series Stainless Valves/
Quicksilver Series Stainless Valves
These valves are stainless, one piece, chrome stem, hard tip,
21-4N EV8, ideal for both competition and street applications.
They are similar in material and design to competition valves,
but manufactured in large production runs for all of the most
popular applications. Because of the fully automated (robotic)
production, SEV-series valves are priced lower than racing models,
yet feature the same premium quality stainless steel
forgings, Chrome stems, stellite tips, and swirl-polishing.
If you do not see a valve you need in the Competition or Silverline
Series, use the Portflow, as they are suitable for these applications. Quicksilvers feature increased undercut stems and thicker margins for increased flow and performance. |
Black Knight Series Stainless Valves
"Black Knight" (code: BK) feature a special coating
that serves two purposes. First, the coating is designed to provide
improved heat transfer. This promotes better valve train life.
Secondly, the coating has proven to combat the problems associated with unleaded gasoline. In short, the Black Knight is what street performance enthusiasts have been waiting for!
